Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627076, here are decompositions:

3 + 31627073 = 31627076
7 + 31627069 = 31627076
43 + 31627033 = 31627076
97 + 31626979 = 31627076
109 + 31626967 = 31627076
193 + 31626883 = 31627076
367 + 31626709 = 31627076
409 + 31626667 = 31627076

Showing the first eight; more decompositions exist.
